What's the difference between parthenogenetic and parthenogenic?
Parthenogenetic
Definition:
(a.) Of, pertaining to, or produced by, parthenogenesis; as, parthenogenetic forms.
Example Sentences:

(6) However, the contribution of parthenogenetic cells to the brain does appear to be influenced by strain background, since a marked improvement in the survival of CFLP, 129 and perhaps SWR parthenogenetic cells in chimeric brains was observed compared with F2 cells.
(7) Prolonged in vitro culture of oocytes after parthenogenetic activation and diploidization treatment showed that formed pronuclei were able to fuse and single prometaphase to telophase mitotic cleavage figures developed in all oocytes fixed 28 h after activation, except one cytochalasin B-treated oocyte with two prometaphase sets of chromosomes.
(8) The presence of duplications in all of these parthenogens, but not among representatives of their maternal sexual ancestors, suggests that the duplications arose in the parthenogenetic form.
(9) Freshly ovulated rabbit oocytes were activated parthenogenetically by periodically repeated calcium stimuli generated by electric field pulses applied onto the plasma membrane.
(10) Two morphologically different generations of nematodes, gamagenetic and parthenogenetic ones, develop in the body cavity of the insects.
(11) Parthenogenetic embryos display a fairly normal development until implantation.
(12) We determined the morphological survival rate, the pattern of parthenogenetic activation, and the microtubular and chromosomal organization.
(13) A high frequency of parthenogenetic activation occurs when ovulated mouse oocytes are briefly exposed to a dilute solution of ethanol in vitro.
(14) By 6.5 days, however, in almost every embryo, parthenogenetically derived cells were not detected in the extraembryonic trophoblast tissue descended from the TE.
(15) Southern blot analysis of all populations shows that they can be grouped into three classes: a) American bisexuals; b) Eurasian bisexuals, and c) parthenogenetic organisms (all from Eurasia).
(16) Despite these losses there has been a large increase in fecundity in the parthenogenetic strain.
(17) Past experiments on teratocarcinoma induction by ectopic grafting of early rodent embryos or fetal germinal ridges have remained ambiguous because embryos ordinarily soon form germ cells, and parthenogenetic germ cells form "embryos."
(18) Oocytes exhibited isolated maturative changes almost exclusively in FSH-LH cultures, such as cortical granule synthesis, resumption of meiosis, polar body extrusion, and two-cell parthenogenetic cleavage.
(19) The parthenogenetic Haemaphysalis longicornis larvae engorged on cattle naturally infected with Theileria sergenti were reared at 24 degrees C. The resultant nymphal ticks were incubated at 37 degrees C to clear the effect of incubation on the development and maturation of sporozoites.
(20) Blebbing exists only in oocytes activated by sperm in vivo or in vitro, or parthenogenetically by treatment with ethanol or puromycin.
Parthenogenic
Definition:
Example Sentences:
(1) The presence of duplications in all of these parthenogens, but not among representatives of their maternal sexual ancestors, suggests that the duplications arose in the parthenogenetic form.
(2) Cyclic parthenogens have made the transition to obligate asexuality with high frequency, but there is little evidence to support the argument (Williams, 1975) that such shifts result from the relaxation of the short-term selection pressures supposedly necessary to sustain the sexual phase of the life cycle.
(3) Although recent extinctions can usually be interpreted as resulting from niche disappearance, the taxonomic distribution of parthenogens suggests that inability to evolve may also be important.
(4) The parthenogens, and thus the duplications, are of recent origin; modifications of the duplicated sequences, particularly by deletion, has therefore been rapid.
(5) 6 h. Changes in the intensity of 3H-thymidine incorporation and in the distribution of radioactive label between haploid and diploid parthenogens were observed.
(6) Restriction enzyme analysis revealed two basic types of mitochondrial DNA (mtDNA) among the parthenogens.
(7) A lower complementation ability of parthenogens may not be an impenetrable barrier to their successful establishment if the invader's genome is relatively uncontaminated by mutant alleles: there are always such genotypes in the sexual population.
(8) organisms in which mating is between different individuals) and obligate selfers or parthenogens lies in the dynamic of the underlying replication process.
(9) The genetic consequences of this transition are not dramatic; the genotypic characteristics of most cyclic parthenogens are similar to those of bisexuals.
(10) In permanent habitats populations of the cyclical parthenogen, Daphnia magna, reproduce by continued parthenogenesis and are subject to only sporadic sexual recruitment.
(11) The current results support the hypotheses that (i) the AH-POA is the major area of hormone action in the brain controlling male-typical sexual behavior in C. inornatus as in other vertebrates and (ii) the neural circuits controlling male-typical behavior have been conserved in the evolution of the parthenogen C. uniparens.
(12) The biological basis of pseudosexual behavior in the parthenogen appears to be due to an unusual sensitivity to ovarian progesterone rather than to a difference in brain morphology.
(13) A hierarchical analysis of population structure in the cyclic parthenogens by using a fixation-index approach indicates that this is one of the most extremely subdivided species yet studied.
(14) Individuals produce clones by means of parthenogenesis, and both diploid and triploid parthenogens exist.
(15) 3H-thymidine was shown to incorporate into pronucleoli of diploid parthenogens and late-labeled heterochromatin blocks were bound in both diploid and haploid pronuclei.
(16) Karyotype analysis from Q-banded preparations revealed that the tumor was parthenogenically derived and exhibited chromosome instability and aneuploidy.
(17) Our results showed no differences in the subunit composition of the thiol proteinase among cysts from eight bisexual strains and four parthenogenic strains, and confirmed an earlier finding that the proteinase is composed of two subunits of 25.9 and 31.5 kilodaltons.
(18) Replication is a linear function of density for obligate selfers or parthenogens but nonlinear for outcrossing sexuals.
(19) In temporary habitats populations of the cyclical parthenogen, Daphnia magna, are re-established each year from sexual eggs and reproduce parthenogenetically for two or at most three generations.
(20) The variation among parthenogens from central to western Australia was similar to that found within local populations of the sexual species that provided the mtDNA, and was an order of magnitude less than the differentiation shown between sexual populations across the same geographic distance.
